Here you can find our range of non-return valves. A non-return valve is used to ensure fluid can only flow in one direction. We offer a number of different types of check valves including swing check valves, spring check valves, duckbill valves, fibreglass valves suitable for use in a wet exhaust and valve flaps.
Swing check valves - These have a flap which will only open in one direction and must be mounted vertical or horizontally.
Spring check valves - Has a spring that lifts in one direction under pressure and can be mounted at any angle.
Valve flaps - Designed to be fitted to cover skin fittings to help prevent water entering the boat.
Duckbill valves - Uses a rubber valve shaped like the beak of a duck. The end of the valve opens under pressure in one direction to allow fluid to pass through and closes when the pressure stops.
